Question

我一直在尝试制作一个应用程序，其中有许多功能与每个按钮相关联。这样，如果我有70个按钮，我有70个不同的功能。我想添加相应的值，当我点击相应的按钮时，到相应的变量标签（我正在使用numericproperty）。由于此函数之间的变化仅在此数值中，我想以比我更加智能的方式进行此操作。如果没有我必须重复我的代码，有没有人建议更好的方法呢？非常感谢大家，我的部分代码也是如此。

的.py

class SegundoScreen(Screen):
    def __init__(self, **kwargs):
        self.name = 'dois'
        super(Screen,self).__init__(**kwargs)

    def mucarela(self, *args):
        screen4 = self.manager.get_screen('carrinho')
        screen4.btn1 = BubbleButton(text="Muçarela", font_size='20dp', size_hint=(1,None), background_normal='1.png', background_down='2.png')
        screen4.lb1 = Label(text="25,00", font_size='20dp', size_hint=(1,None))
        screen4.ids.lb5.value += 25
        screen4.ids.grid.add_widget(screen4.btn1)
        screen4.ids.grid.add_widget(screen4.lb1)

    def catupiry(self, *args):
        screen4 = self.manager.get_screen('carrinho')
        screen4.btn2 = BubbleButton(text="Catupiry",font_size='20dp', size_hint=(1,None), background_normal='2.png', background_down='1.png')
        screen4.lb2 = Label(text="25,00",font_size='20dp', size_hint=(1,None))
        screen4.ids.lb5.value += 25
        screen4.ids.grid.add_widget(screen4.btn2)
        screen4.ids.grid.add_widget(screen4.lb2)

    def peru(self, *args):
        screen4 = self.manager.get_screen('carrinho')
        screen4.btn2 = BubbleButton(text="Peito de peru",font_size='20dp', size_hint=(1,None), background_normal='1.png', background_down='2.png')
        screen4.lb2 = Label(text="95,00",font_size='20dp', size_hint=(1,None))
        screen4.ids.lb5.value += 35
        screen4.ids.grid.add_widget(screen4.btn2)
        screen4.ids.grid.add_widget(screen4.lb2)

我有一个类表单，它只是一个标签numericpropertie，它在单击相应按钮时更改了值。由于更改仅在此标签中，因此我将锁定如何从文本标签中获取价格值，并从文本按钮中获取flavor名称。非常感谢。

对于你的.kv文件，我建议使用像

这样的类

Route::get('/edisi/{id}', 'JurnalController@store');
Route::resource('jurnals', 'JurnalController');

然后在你的代码中你可以使用MyButton的实例，它可以稍微缩小你的代码。

我怎样才能避免在python / kivy中重复？
